I have a website where users can upload images.

once the image is processed,and whenever someone tries to screenshot, print screen... i want a black image to be appeared ( only the image to be blackened and not the whole screen) and also it applies to any Operating system used.

is this possible? if possible can i have the codes please?

What I have tried:

i have tried some plugins in word press but the plugin blocks the screenshot itself and i have researeched some codes but in vain

It is not possible. You can limit right clicks and various other methods, but sad truth is that whatever you try you cannot prevent downloading completely because you have to download images to show them. I could find them in tmp folder if nothing else.

What you CAN do is put watermark over the images to protect them from simple download. It will make it harder for the potential thief to use them. Complex watermark that is hard to remove is the best (cris-crossing lines with text in the middle with shadow or some repeating pattern for example)

i mean the user will print screen it, obviously it will paste it in paint for example,and of course he will obtain the print screen but the processed image will appear black. Also applied to any OS

is that one possible?
thanks in advance
